Is there a full body scan to detect cancer?

Can a full body scan detect cancer?

That's because there is no evidence that the scans are a good screening tool. Whole-body scans find cancer tumors in less than two percent of patients without symptoms. Whole-body scans can miss signs of cancer. The tests that are recommended—like mammograms—would probably find these signs.

Can a full body CT scan detect cancer?

CT scans can detect bone and joint problems, like complex bone fractures and tumors. If you have a condition like cancer, heart disease, emphysema, or liver masses, CT scans can spot it or help doctors see any changes. They show internal injuries and bleeding, such as those caused by a car accident.
